Thousands of tourists visit Ladakh every year, without encountering any problems due to the altitude. Nevertheless, mountain sickness can be troublesome and it is therefore important to follow a few simple rules in order to allow the body to adapt itself to the altitude.
The first rule in order to acclimatise well is that you must rest, or at least avoid physical exertions during the first two days. This is particularly true for walkers. On our voyage, there are no physical exertions planned, and we will be travelling by bus, this therefore ought not to pose a problem.
Benign but common symptoms upon arrival include headaches which disappear rapidly if you rest. It is also important to drink lots and to pay attention to your general health. If strong headaches continue or get worse, with other symptoms such as vomiting, then you must absolutely return to lower altitudes (500m at most).
In conclusion, there is no reason to panic, but you must remain cautious ! In any case, we will always be accompanied by a local guide who will know exactly what advice is useful and will be able to direct us to a doctor should that be required.
If this possibility still worries you, remember that the best way to prevent problems due to the acclimatisation is to organise a few excursions at altitude (between 3000 and 35000m) in the weeks leading up to the voyage, for example in the Alps.
